Keywords:Optical manipulation, Optical force, Polystyrene particle

In this study, we discuss theoretically an enhancement of scattered light form a Polystyrene particle array and its spatial structure. The array is optically trapped by a single focal laser. When the array is hexagonal package, the scattered light is enhanced in six directions. For tetragonal one, the scattering is in for. We evaluate the optical force on each particle due to the scattered light and find qualitative agreement with a forming of “horns” from the array.
